Ignition
Quality Test

(ASTM D6890-12) Southwest Research Institute

Southwest Research Institute performed Ignition Quality Tests (IQT™) ASTM D6890-12 on Synergyn® XTrA MMPG Fuel Saver at its San Antonio facilities in November 2014. This industry bench test for diesel engines measures diesel fuel combustion efficiency using a combustion vessel with volume, pressure and temperature similar to a single cylinder of a 12-liter heavy-duty diesel engine.

Synergyn® Starts Combustion Sooner

The shorter Ignition Delay and higher Derived Cetane Number in the test measurements demonstrated that combustion starts sooner with Synergyn® XTrA MPG:

Ignition Delay: the time between the start of injection and the first identifiable pressure increase during combustion of the fuel.

The speed at which the fuel burns in the cylinder (measured by pressure versus time) matters because the faster combustion:

Generates more energy and power sooner,

Burns the fuel more completely--increasing the energy released and converting more potential energy into useable energy, and

Reduces the amount of unburned and partially burned fuel in the exhaust gases.

The graph shows pressure in pounds per square inch versus time, after injection, in milliseconds and shows that Synergyn® XTrA MPG in ULSD (blue curve) creates more pressure earlier in the combustion cycle when the piston would be closer to top dead center of the engine cylinder. In addition, the Combustion Gradient (slope of the curve) is considerably superior for Synergyn® compared to ULSD as demonstrated by the steeper slope of the blue curve compared to ULSD—the black curve. We can see that Synergyn® is releasing more energy faster because the pressure is greater all along the curve.

Thus, the higher Combustion Chamber Pressure and faster burn in the IQT shows that Synergyn® increases the speed of combustion.

Synergyn® Releases Energy Faster

There is a dramatic improvement in Cumulative Energy Released by Synergyn® XTrA MPG™ Fuel Saver versus ULSD. The faster energy release from Synergyn’s combustion enhancing chemistry is seen in the graph below; it provides scientific evidence that energy is being released faster and that consumers should see a reduction in fuel consumption on the road.
